Title: Improvements in or relating to the production of sintered bodies
Inventor: BLAINEY ALAN
IPC: B22F3/12
Filed: 1947-12-01
Abstract: Shaped bodies of metals or electrically conducting metal compounds are formed by placing a mass of particles of the metal or compound in a confined space and compressing it while it is heated by an electric current passing through the mass, a substance being present which is vaporizable under the conditions of and during the heating and compacting stage.  Uranium turnings may be crushed to flakes and then ball-milled in paraffin oil. The resulting mass of particles coated with oil is introduced into a silica tube closed by copper plungers at both ends and heated under a light pressure by passage of an electric current between the plungers which may be tipped with graphite discs.  When the particle mass has reached a uniform temperature corresponding to the softening temperature the plungers are driven together by impact at a pressure of .5-1 ton per square inch.  The rod so formed may be lengthened by adding to its end further uranium particles which are similarly treated or by stringing together a number of such rods in a silica or other tube, heating and impacting to join them.  Beryllium, tungsten and hard metal carbides with or without binding metals such as cobalt may be similarly treated.

Title: Improvements in or relating to the printing of fabrics
Inventor: GRIFFITHS JACK
Filed: 1958-10-07
Abstract: Textile materials are printed with a dyestuff and treated with a reducing agent before being passed around a system of heated rotating cylinders.  The materials are held against part of the periphery of each cylinder by a travelling band of fluid-tight material and are passed substantially directly from the peripheral surface of one cylinder to that of the next whereby the dyestuff is reduced to a soluble form and the cylinder surfaces are continuously cleaned at another part of their peripheries. Apparatus suitable for treating the textile materials as above is shown in Fig. 1 of the drawing and comprises a plurality of rotatable cylinders 11, 12 having internal heating means, e.g. steam, an endless band of fluid-tight material 24, means for supporting the band around part of the periphery of each cylinder, e.g. rollers 13-23, means for introducing the textile material between those parts of the cylinder surfaces and the band, e.g. a further set of rollers 31-35 and means 37 for continuously cleaning the periphal surfaces of the cylinders at another part of their peripheries when rotating.  Additionally means may be provided for continuously cleaning the travelling band after it leaves the last cylinder and before it reaches the first cylinder. As shown in Fig. 1a, reservoir 30 and padding mangle rolls 27, 28 are disposed so as to enable printed and padded fabric 29 to be fed to the cylinders 11, 12 in association with the band 24.

Abstract: 761,735. Gas manufacture. POWER-GAS CORPORATION, Ltd. July 25,1955 [Nov. 5, 1954], No. 32021/54. Class 55 (2). In the continuous production of oil-gas, a fuel is combusted in a stream of steam to produce a mixture of superheated steam and products of combustion with a temperature of at least 1200‹ C. and preferably above 1350‹ C., and then causing the mixture to react with a petroleum oil in the form of an oil vapour or an atomized liquid. The process may be effected at high pressure, e.g. 20 atmospheres. A vertical chamber 1 is provided with a steam inlet 2 at the bottom, and a fuel burner 5 close thereto. Oxygen-rich gas is supplied at 7 and fuel at 6. Petroleum vapour is projected downwardly at 4 and the product gas leaves at 3. In a modification, the steam inlet and burner are at the top of the chamber and the oil supply and outlet are at the bottom. In another form, the steam inlet and burner are at the bottom of the chamber and the steam/combustion-products mixture is lead to another chamber in which it is reacted with a downward oil spray, the oil-gas leaving at the bottom of the latter chamber. The temperature at which the reaction takes place is varied according to the desired composition of the oil-gas, but is generally between 600‹ and 900‹ C. Some of the product oil-gas may be re-cycled as fuel gas either before or after cooling to condense out unreacted steam. The steam, oxygen-rich gas, fuel, and oil may be preheated by heat-exchange with the product gas. If pulverulent fuel is used in the burner, one or more cyclones are used for removing ash from the product gas.
